Improved machine for stamping reed-plates



UNITED SrrrrEs CHARLES AUSTIN, OF CONCORD, NEW HAMPSHIRE.

IMPROVED MACHINE FOR STAMPING REED-PLATES.

Specification forming part of Letters Patent No. 59,541, dated November13, 1866.

To alt whom it may concern Be it known that l, OHARLEs AUs'rIN, ofConcord, in the count y of Merrimack and State of New Hampshire, haveinvented a new and useful Machine for Stamping Reed- Plates from a Sheetof Metal; and I do hereby declare the same to be fully described in thefollowing specification and represented in the accompanying drawings, ofwhich- Figure 1 is a top view, Figs. 2 and 3 longitudinal sections, andFig. 4E a transverse section, of it. Fig. 5 is a top view of a reedplateas made by such machine.

lhe design of such machine is to convert a sheet of metal into a seriesof reed-plates formed with sockets for holding the reeds of a inelodeonor seraphine.

InV the drawings, A denotes the frame of the machine, it consisting of abed-plate, a, Iand a goose-neck77 or standard, b, the latter heilig'erected 011 and projected from the bedplate, and formed as represented.The said standard serves to support and guide a plunger, B, which is tobe arranged over the bed-plate, and applied to the standard so as to becapable of being moved vertically either toward or away from the bed.

The plunger carries two male dies, C D, one of which-wiz., that markedC-is arranged in a groove, x, made in the plunger, and fastened thereinby a set-screw, y. rIhe other die is fixed in an adjustable carrier, E',which is to be secured to the plunger in such manner as to be'capable ofbeing moved in the plunger so as to adjust the male die D either towardor away from the die C. These dies operate with female die-plates E F,placed underneath them and supported in other carriers or carriages, GH, resting on the bed;

Adjusting-screws d d d d screw through ledges e e, raised on the bed.These screws act against opposite sides of the carrier G, and serve ,toadjust it properly with respect to the larger male die. rIhe othercarrier, H, is contned to the bed by means of set-screws fj', which gothrough slots g g made transversely in the carrier. Each of suchcarriers is grooved lengthwise for the receptian of a dieplate, in orderthat'the machine may be adapted to the use of dies of different sizes.

Furthermore, each carrier Gr H has a vertical passage, It, made downthrough it, and to open into a similar but larger passage, t', made downthrough the bed, such passages being for discharging the metal forceddown through the female dies.

The plunger and its movable die-carrier E are also to be so made as tobe capable-of holding dies for making reed-plates of different sizes. Astop-ledge, Z, projects upward from the die-plate E and close to therearmost edge of its opening or female die.

In operating with the above-described machine, a sheet of metal is to belaid underneath both ofthe male dies and on the female die-plates, andso that its edge may be against the inner edge of the ledge or gage l,after which the plunger should be forced downward, so as tosimultaneously separate from the plate two pieces of metal correspondingin form with the female dies. One of these pieces will be of the shapeof' the plate shown in Fig. 5, except that it will be without any holeor passage through it. The other will be of the shape of the opening ofsuch reed -plate. Next, the sheet of metal is to he advanced so as tobring its rear edge up to the gage l, and the plunger should again bedriven downward. rIwo pieces of metal will thus again be separated fromthe sheet. One of these pieces will be of the exact shape of thereed-plate, while the other will be of the shape of the opening of suchreed-plate. .Continuing to proceed in this manner, the whole sheet maybe reduced to reed-plates and pieces of the shape of the openingsthereof.

I claim- 1.` The combination and arrangement of theA gage l, the twosets of male and female dies, and the adjustable die-carrier, applied toa bed and plunger so as to operate substantially as and for the purposeset forth.

2. The combination and arrangement of the three adjustable die-carriersE G H with the bed and plunger and 'its fixed or larger die, suchdie-carriers b eing provided with mechanism for adjusting them,substantially as set forth.

CHARLES AUSTIN.
